What I basically mean, is a sprite leaving behind tinted "copies" of itself. It's a pretty damn cool effect. This vid is filled with this:
To do this in Construct now would require extra objects and events, but if it was added as an actual feature, users could easily set the effect to particular animations and with different settings for each one. From what I can see, there's three ways this can be applied:
1. The character leaves the copies behind as he/she moves, and they disappear.
2. The copies follow the character closely behind, and then rejoin up with him/her when the animation is finished.
3. It could also be used to created a copy larger than the character, as an "aura" of sorts,
and Gouken does a variant of this in the earlier vid.
So, good idea, or no?
